Abstract. A new tribe of digger wasps, Rasnitsynapini trib.n. (Hymenoptera: Crabronidae, Pemphredoninae), which includes the only known genus and species Rasnitsynapus primigenius gen. et sp.n., is described from the Upper Cretaceous New Jersey amber. The most distinctive characters of the new tribe include complete wing venation, non-elongate first gastral segment without separated sternal petiole, and absence of psammophores, digging tarsal rakes, and pygidial plate. The new tribe occupies a basal position in the phylogenetic tree of the subfamily Pemphredoninae and also represents a sister group to the tribe Spilomenini which is separated from the tribe Pemphredonini. The extinct genus Palanga Budrys is placed within a new tribe, Palangini trib.n. A list of extinct and extant genera of the subfamily Pemphredoninae and a scheme of their probable phylogenetic relationships are proposed.
